SysOperation framework. Update dialog caption in UIBuilder

on

Step 1. Add buildCaption and updateCaption methods

private void updateCaption(EnumType _enumValue)
{
    str caption = this.buildCaption(_enumValue);
    FormRun formRun = (dialog as Dialog).formRun() as FormRun;
    FormDesign design = formRun.design();
    design.caption(caption);
}

private str buildCaption(EnumType _enumValue)
{
    return strFmt('%1 - %2',
        "@LabelId",
        enum2Symbol(enumNum(EnumType), _enumValue));
}

Step 2. Override postBuild to get contract reference

public void postBuild()
{
    super();

    contract    = this.dataContractObject() as SampleDataContract;
    dfEnumField = this.bindInfo().getDialogField(contract, methodStr(SampleDataContract, parmEnumField));

    dfEnumField.registerOverrideMethod(
        methodStr(FormComboBoxControl, modified),
        methodStr(SampleUIBuilder, enumField_OnModified),
        this);
}

Step 3. Call from postRun

public void postRun()
{
    super();
    this.updateCaption(contract.parmEnumValue());
}
